Technologies for dynamic telematics message parsing

ABSTRACT

Technologies for dynamic telematics message parsing include a telematics cloud server that receives a message definition and generates a dynamic message parser based on the message definition. The message definition may be a binary structure definition. A telematics device receives a message data payload from a peripheral device of a vehicle and then transmits a device message including the message data payload to the cloud server. The peripheral device may include a sensor or a controller coupled to the vehicle. The cloud server executes the dynamic message parser with the message data payload and generates a standardized data structure. The standardized data structure may be processed using a telematics cloud platform. Other embodiments are described and claimed.

Referring now to FIG. 1 , an illustrative system 100 for dynamic telematics message parsing includes a telematics cloud server 102, which may be in communication with multiple assets 104 and vendor workstations 106 over a network 108. In use, as described further below, the telematics cloud server 102 receives a message definition from a vendor workstation 106 and then generates a corresponding dynamic message parser. A telematics device 140 coupled to an asset 104 sends one or more messages including telematics data to the telematics cloud server 102, and the telematics cloud server 102 executes the dynamic message parser to parse the messages and process the corresponding message data. Accordingly, the system 100 may process messages from multiple peripheral devices from different vendors without modifying application programming interface (API) code on the telematics cloud server 102. Accordingly, the telematics cloud server 102 may support many different sensors or other peripheral devices from multiple vendors without requiring custom code for each specific peripheral device. Thus, integration time may be reduced, which may reduce costs and/or increase capabilities of applications built with the telematics cloud server 102.

The telematics cloud server 102 may be embodied as any type of device capable of performing the functions described herein. For example, the telematics cloud server 102 may be embodied as, without limitation, a server, a rack-mounted server, a blade server, a workstation, a network appliance, a web appliance, a desktop computer, a laptop computer, a tablet computer, a smartphone, a consumer electronic device, a distributed computing system, a multiprocessor system, and/or any other computing device capable of performing the functions described herein.

Thus, each of the vendor workstation 106 includes components and devices commonly found in a computer or similar computing device, such as a processor, an I/O subsystem, a memory, a data storage device, and/or communication circuitry. Those individual components of the vendor workstation 106 may be similar to the corresponding components of the telematics cloud server 102, the description of which is applicable to the corresponding components of the vendor workstation 106 and is not repeated herein so as not to obscure the present disclosure.

As discussed in more detail below, the telematics cloud server 102, the telematics devices 140, and the vendor workstations 106 may be configured to transmit and receive data with each other and/or other devices of the system 100 over the network 108.

For example, the network 108 may be embodied as, or otherwise include, a wired or wireless local area network (LAN), a wired or wireless wide area network (WAN), a cellular network, and/or a publicly-accessible, global network such as the Internet. As such, the network 108 may include any number of additional devices, such as additional computers, routers, stations, and switches, to facilitate communications among the devices of the system 100.

Referring now to FIG. 2 , in the illustrative embodiment, the telematics cloud server 102 establishes an environment 200 during operation. The illustrative environment 200 includes a cloud telematics platform 202, a configuration interface 206, a data adapter 210, a parser manager 214, and a message processor 218. The various components of the environment 200 may be embodied as hardware, firmware, software, or a combination thereof. As such, in some embodiments, one or more of the components of the environment 200 may be embodied as circuitry or a collection of electrical devices (e.g., cloud telematics platform circuitry 202, configuration interface 206, data adapter circuitry 210, parser manager circuitry 214, and/or message processor circuitry 218). It should be appreciated that, in such embodiments, one or more of those components may form a portion of the processor 120, the I/O subsystem 122, and/or other components of the telematics cloud server 102.

The configuration interface 206 is configured to receive a message definition 208 indicative of a binary message format. In some embodiments, the binary message format may be embodied as a binary structure definition. The message definition 208 may be received from a remote computing device such as a vendor workstation 106.

The parser manager 214 is configured to generate a dynamic message parser 216 as a function of the message definition 208. The parser manager 214 may be further configured to deploy the dynamic message parser 216 after generation. Deploying the dynamic message parser 216 may include associating the dynamic message parser 216 with a predetermined message code.

The message processor 218 is configured to receive a device message 220 from a vehicle telematics device 140. The device message 220 includes a message code and a message data payload. The message data payload may be generated by an asset 104, a component of the asset 104 such as a controller 144, or a sensor 146 coupled to an asset 104.

The message processor 218 may be further configured to identify the dynamic message parser 216 for execution based on the message code of the device message 220. Executing the dynamic message parser 216 may include extracting a data item from the message data payload, determining a label associated with a data item, or converting a data item to another data item using a predetermined data conversion operation.

The data adapter 210 is configured to generate a standardized data structure 212 as a function of the message data payload in response executing the dynamic message parser 216. Generating the standardized data structure 212 may include generating a standardized data structure that includes a data item extracted by the dynamic message parser 216, a label that is determined by the dynamic message parser 216, or another data item that results from a conversion performed by the dynamic message parser 216. The standardized data structure 212 may conform to a predetermined vehicle telematics schema associated with the cloud telematics platform 202. In some embodiments, the standardized data structure 212 may include a text-based format such as a JavaScript object notation (JSON) format or an extensible markup language (XML) format.

The cloud telematics platform 202 may be embodied as a multi-tenant application environment or other cloud application platform. The cloud telematics platform 202 is configured to process the standardized data structure 212. Processing the standardized data structure 212 may include providing the standardized data structure 212 to a cloud application 204 executed by the cloud telematics platform 202.

Referring now to FIG. 2 , in the illustrative embodiment, the telematics device 140 establishes an environment 240 during operation. The illustrative environment 240 includes message generator 242. The various components of the environment 240 may be embodied as hardware, firmware, software, or a combination thereof. As such, in some embodiments, one or more of the components of the environment 240 may be embodied as circuitry or a collection of electrical devices (e.g., message generator circuitry 242). It should be appreciated that, in such embodiments, one or more of those components may form a portion of the processor, the I/O subsystem, and/or other components of the telematics device 140.

The message generator 242 is configured to receive messages from a peripheral device coupled to the telematics device 140 such as a controller 144 or a sensor 146 of an asset 104. The message generator 242 is further configured to forward the message received from the peripheral device to the cloud telematics server 102 as the message data payload of a device message 220.

Referring now to FIG. 3 , in use, the telematics cloud server 102 may execute a method 300 for generating and deploying a dynamic parser. It should be appreciated that, in some embodiments, the operations of the method 300 may be performed by one or more components of the environment 200 of the telematics cloud server 102 as shown in FIG. 2 . The method 300 begins with block 302, in which the telematics cloud server 102 receives a message definition 208 from a vendor workstation 106. The message definition may be embodied as a declarative description of the format of binary messages generated a peripheral device such as a controller 144, a sensor 146, or another device that may be incorporated in or otherwise coupled to an asset 104 in communication with a telematics device 140. The message definition 208 may be generated by the vendor workstation 106, for example, when deploying or otherwise preparing a peripheral device for use with the cloud telematics platform 202. In some embodiments, in block 304, the telematics cloud server 202 may receive the message definition 208 as a binary structure definition. For example, the message definition 208 may be embodied as a Kaitai Struct file, a .KSY file, or other description of a binary structure format.

In block 306, the telematics cloud server 102 dynamically generates a message parser 216 based on the message definition 208. The message parser 216 may be embodied as executable code, object code, bytecode, a script file, a parser table, or other data that may be executed by the telematics cloud server 102 to parse device messages according to the message definition 208. The message parser 216 is dynamically generated and thus may be loaded and executed at runtime. Accordingly, in some embodiments the message parser 216 may be executed without updating firmware of one or more telematics devices 140.

In block 308, the telematics cloud server 102 automatically deploys the dynamically generated message parser 216. Deploying the dynamically generated message parser 216 allows the cloud server 102 to execute the message parser 216 when processing device messages received from telematics devices 140. The message parser 216 may be deployed on demand (e.g., using just-in-time compilation or other runtime deployment) or using any other deployment strategy. In some embodiments, in block 310 the telematics cloud server 102 may associate the dynamic message parser 216 with a message code. The message code may be a predetermined eight-bit value or other constant, and in some embodiments may be supplied or otherwise specified by the vendor workstation 106. Additionally or alternatively, the message code may be embodied as any predetermined metadata included in the device message and/or extrinsic data associated with the device message such as network port number, network protocol, or other information or characteristics associated with the device message but not included in the device message. As described further below, the telematics cloud server 102 may use the message code to identify a particular dynamic message parser 216 for use in parsing a particular device message. Accordingly, in some embodiments the message parser 216 may be deployed without modifying API code of the telematics cloud server 102. In block 312, the telematics cloud server 102 may override one or more inherited message definitions. For example, the telematics cloud server 102 may override a default definition or other previously provided message definition that matches the name or other identifier of the message definition 208 provided by the developer/vendor workstation 106. In some embodiments, the provided message definition may override a default definition for one or more elements of the message definition (e.g., for one or more indices or other positions in the binary message). After deploying the message parser 216, the method 300 loops back to block 302 to continue processing message definitions 208.

Referring now to FIG. 4 , in use, a telematics device 140 may execute a method 400 for processing device messages. It should be appreciated that, in some embodiments, the operations of the method 400 may be performed by one or more components of the environment 240 of the telematics device 140 as shown in FIG. 2 . The method 400 begins with block 402, in which the telematics device 140 receives an arbitrary message from a connected device. The message may be a binary message or other data and may have an arbitrary message format. As described above, this format of the binary message may be described by a corresponding message definition 208 that is provided to the telematics cloud server 102. The connected device may be a peripheral device of an asset 104 such as a controller 144 or a sensor 146. Accordingly, the message may be received over the vehicle bus 142 or may be received directly from the connected device. In some embodiments, in block 404 the telematics device 140 may receive the message from the asset 104 or from a component of the asset 104 (e.g., a vehicle controller 144). In some embodiments, in block 406 the telematics device 140 may receive the message from a sensor device 146.

In block 408, the telematics device 140 forwards the message to the cloud telematics server 102. The telematics device 140 may transmit the message to the telematics server 102 via the network 108, for example using cellular network connectivity, long-range radio connectivity, or other network communications. The message may be embodied as a user message, an application message, a data packet, or any other message that conforms to the message definition 208 as described above. In some embodiments, in block 410 the telematics device 140 may send the message as a device message 220 with a predetermined message code. As described above, the message code may be a predetermined byte value or other constant, a predetermined metadata element included in the device message, and/or an extrinsic data element associated with the device message such as network port number, network protocol, or other information about or characteristics associated with the device message 220. The binary message received from the connected device may be included in the device message 220 as the message data payload. For example, in an embodiment, the telematics device 140 may send fleet management interface (FMI) messages received from a GPS receiver 146 to the telematics cloud server 102 as user messages. Similarly, in an embodiment, telematics device 140 may send automatic vehicle localization (AVL) sensor data received from other sensors 146 to the telematics cloud server 102 as user messages. The device message 220 is processed by the telematics cloud server 102 as described further below in connection with FIG. 5 . After forwarding the message, the method 400 loops back to block 402 to continue processing additional messages from the connected device.

Referring now to FIG. 5 , in use, the telematics cloud server 102 may execute a method 500 for dynamically parsing device messages. It should be appreciated that, in some embodiments, the operations of the method 500 may be performed by one or more components of the environment 200 of the telematics cloud server 102 as shown in FIG. 2 . The method 500 begins with block 502, in which the telematics cloud server 102 receives a device message 220 from a telematics device 140. The device message 220 includes a message data payload, which may include vehicle telematics data or other data collected and/or generated by the telematics device 140. In some embodiments, in block 504 the telematics cloud server 102 may receive a device message 220 that includes a predetermined message code. The device message 220 may be embodied as a network message such as a UDP message or other data packet, and the message code may be embodied as an 8-bit field included in a header or at another predetermined location in the device message 220. Of course, in other embodiments the device message 220 may use a different protocol and/or message format. In some embodiments, in block 506, the message data payload included in the device message 220 may be generated by the asset 104 or a component of the asset 104, such as a controller 144. In some embodiments, in block 508, the message data payload included in the device message 220 may be generated by a sensor 146 of the asset 104.

In block 510, the telematics cloud server 102 identifies a dynamically generated message parser 216 to use for parsing the device message 220. The dynamically generated message parser 216 is generated from a message definition 208 as described above in connection with FIG. 3 . The telematics cloud server 102 may use any appropriate technique to identify the message parser 216. In some embodiments, in block 512 the telematics cloud server 102 may identify the dynamic message parser 216 based on the message code included in the device message 220. For example, as described above, the message code may be a predetermined byte constant or other predetermined value that is associated with the dynamic message parser 216 during deployment. The telematics cloud server 102 may match the message code against predetermined values associated with multiple dynamic message parsers 216 in order to identify a particular dynamic message parser 216 for use in parsing the device message 220. As another example, the telematics cloud server 102 may identify the dynamically generated message parser 216 by matching a network port number associated with the device message 220 against predetermined port number values associated with multiple dynamic message parsers 216.

In block 514, the telematics cloud server 102 executes the identified dynamic message parser 216 with the message data payload of the device message 220. During execution, the message parser 216 may read one or more data fields from the device message 220, generate one or more labels, perform data conversions, or perform other operations defined by the message definition 208. In some embodiments, in block 516 the message parser 216 executed by the telematics cloud server 102 may extract one or more data items from the message data payload. For example, for each data item the message parser 216 may extract a certain number of bytes, bits, or other data from a predetermined location in the message data payload. The message parser 216 may, for example, extract data in a particular numeric format (e.g., integer, floating point, signed, unsigned, etc.) and/or endianness. As another example, the message parser 216 may extract textual data in a string format and/or encoding (e.g., UTF-8, UTF-16, or other encoding). In some embodiments, in block 518 the message parser 216 executed by the telematics cloud server 102 may label one or more fields or other extracted data items. For example, the message parser 216 may associate one or more predetermined labels, titles, descriptions, offsets, or other metadata with an extracted data item. In some embodiments, in block 520 the message parser 216 executed by the telematics cloud server 102 may convert data between formats, units, or perform other conversions or translations. For example, the message parser 216 may convert a value in one unit (e.g., miles per hour) into another value in a different unit (e.g., kilometers per hour). As another example, the message parser 216 may convert a dimensionless binary value into a distance value in certain units (e.g., miles or kilometers), a speed value in certain units (e.g., miles per hour or kilometers per hour), or perform other conversions. In some embodiments, in block 522 the message parser 216 executed by the telematics cloud server 102 may perform one or more calculations with message data. The message parser 216 may, for example, perform one or more numerical, lexical, logical, or other operations included in the message description 208.

In block 524, the telematics cloud server 102 generates a standardized data structure 212 based on the results of executing the dynamic message parser 216 with the message data payload. For example, the telematics cloud server 102 may generate a standardized data structure 212 that includes data extracted from the message data payload, labels generated by the message parser 216, and/or the results of data conversion or other calculations performed by the dynamic message parser 216. The standardized data structure 212 may be embodied as any data format that may be processed by the cloud telematics platform 202 of the telematics cloud server 102. For example, the standardized data structure 212 may conform to a vehicle telematics schema or other predetermined interface compatible with the cloud telematics platform 202. In some embodiments, in block 526 the telematics cloud server 102 may generate the standardized data structure 212 as a JavaScript object notation (JSON) object. In some embodiments, in block 528 the telematics cloud server 102 may generate the standardized data structure 212 as an extensible markup language (XML) document or other XML data.

In block 530, the telematics cloud server 102 processes the standardized data structure 212 with the cloud telematics platform 202. The telematics cloud server 102 may enrich, log, aggregate, analyze, or otherwise process the telematics data included in the standardized data structure 212. In some embodiments, in block 532 the telematics cloud server 102 may provide the standardized data structure 212 to one or more cloud applications 204 executed in connection with the cloud telematics platform 202. For example, the standardized data structure 212 may be executed by a cloud application 204 provided by a vendor that also provided the message definition 208 associated with the message data payload transmitted by the telematics device 140 (e.g., from a peripheral device such as a controller 144 and/or a sensor 146). After processing the standardized data structure 212, the method 500 loops back to block 502 to continue processing messages from the telematics device 140.
